Darstellung von Fluorjodsilanen (über Halogenaustauschreaktionen) und ihre spektroskopische Charakterisierung. Spektren von SiBrCl2F und SiBr2ClF

摘要

Br/I-exchange reactions between some bromofluorosilanes and HSiI3lead to the hitherto unknown fluoroiodosilanes SiFCl2I, SiFClI2, SiFBr2I SiFBrI2, and SiF2BrI as well as SiFI3and SiF2I2. The19F-NMR data and vibrational spectra (including assignments) of these compounds and of SiFCl2Br and SiFClBr2are reported and discussed.
